Ubuntu adjusts space that uses LVM

My MongoDB can’t start today. My server is Ubuntu 22. When I checked the logs that said ‘No space left on device’. I guess maybe when installling Ubuntu they use LVM. Below is adjusted space.

1. Check device

df -h

2. Check LVM information

vgdisplay

3. Adjusts device

lvextend -L 10G /dev/mapper/ubuntu--vg-ubuntu--lv      # adjusts 10G
lvextend -L +10G /dev/mapper/ubuntu--vg-ubuntu--lv     # add 10G
lvreduce -L -10G /dev/mapper/ubuntu--vg-ubuntu--lv     # reduce 10G
lvresize -l  +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv   # use percentage

You can use any of the four ways to adjusts your device.

4. Resize device

resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv

5. Double check

vgdisplay

df -h

All set.
